DP4.8II

Based on powerful DSP digital audio processor, it is an ideal choice for engineering installation applications, it combines the functions of traditional equipment with remote control capabilities, especially suitable for party rooms, electronic music rooms, bars, hi rooms, and Performance and sound reinforcement system.

Extraordinary sound quality performance. Based on the 192kHz digital sampling rate, it provides an audio bandwidth of more than 35kHz. The high-frequency resolution performance is delicate, the frequency domain expansion is wide, and the audio content is truly restored. Supports linkage adjustment between channels, supports optional security lock settings, supports Extended Simple Remote Communication Protocol
